Hi,
On one of my servers, the most basic thing doesn't work and after 2 days of
unsuccessful digging in my severs and the Internet, I'm desperate enough to
write to this list :)
Ubuntu server with kernel 3.19.0-33-generic #38~14.04.1-Ubuntu has p2p1.17
physical interface attached to bri17 bridge. When I start some LXC container, it
creates for ex. vethPQORXD interface and adds it to bri17 bridge. It looks like
this:
# brctl show bri17
bridge name bridge id STP enabled interfaces
bri17 8000.00163eaaaa30 no p2p1.17
vethPQORXD
LXC container's eth0 interface (linked to vethPQORXD) has mac 00:16:3e:aa:aa:66.
When I add IP do this eth0 and ping something to generate eth frame, that mac is
learned on p2p1.17 port instead of vethPQORXD:
# brctl showmacs bri17
port no mac addr is local? ageing timer
1 00:16:3e:aa:aa:66 no 112.50
[... some other macs ...]
1 3c:fd:fe:01:ee:e0 yes 0.00
1 3c:fd:fe:01:ee:e0 yes 0.00
2 fe:56:74:59:a4:9e yes 0.00
2 fe:56:74:59:a4:9e yes 0.00
Of course it makes communication of outside world with that container impossible
(host<->container works).
Any ideas why this happens?
